Arizona Laws 48-1601. District warrants
A. No claim shall be paid by the district treasurer until it has been allowed by the board of directors, and then only upon warrants signed by the president and countersigned by the secretary. The warrants shall state the date when the claim was allowed by the board and from what funds payable. If the district treasurer does not have sufficient money in the fund to pay the warrant when it is presented for payment, he shall endorse thereon the date when presented and the words, "not paid for want of funds – -this warrant draws interest from this date at six per cent per annum," and sign the endorsement. The warrant shall draw interest at the rate of six per cent per annum from the date of endorsement until paid.
B. When the warrant is first presented for payment, if there is any money in the fund upon which the warrant was drawn, the money shall be applied and endorsed thereon and the warrant registered for the unpaid balance only.
C. All claims against the district shall be verified in the same manner as claims against counties, and upon filing the claim it shall be numbered consecutively by the secretary and filed in the office of the district. The secretary of the district is authorized to administer oaths to the persons verifying claims with the same authority as a notary public.
D. The district treasurer shall keep a separate district register in which he shall enter each warrant presented for payment, showing the date and amount of the warrant, to whom payable, the date of presentation for payment, the date of payment, and the amounts paid in redemption thereof. Warrants shall be paid in the order of their presentation for payment to the district treasurer. The warrants shall be drawn payable to the claimant or order in the same manner as county warrants.
